If you want to make your home as energy-efficient and green as possible, should you use gas or electric for your heating and cooling needs? Gas is the more eco-friendly option—for now—for an energy-efficient home in Maryland. ...

Could the health benefits and reduced costs to healthcare systems be enough to justify subsidizing charging infrastructure to allow society to switch from the internal combustion engine to electric vehicles faster than current ...

For the first time ever, researchers have measured the fidelity—that is, the accuracy—of two-qubit logic operations in silicon, with highly promising results that will enable scaling up to a full-scale quantum processor.

Logic and memory devices, such as the hard drives in computers, now use nanomagnetic mechanisms to store and manipulate information. Unlike silicon transistors, which have fundamental efficiency limitations, they require ...

Kevin Leiser starts with his eyes closed and his back to the target. As he turns and raises the compound bow, he keeps his eyes shut, listening to the beeping in his headphones. He adjusts his aim until the beeps merge into ...

A new study carried out by University College Dublin (UCD) academics, published today, has revealed that in typical Irish commuting conditions, Toyota's hybrid powertrain system drives in zero emissions mode (ZEV) for significantly ...

If you have ever wondered how much electric vehicle (EV) adoption actually matters for the environment, a new study provides evidence that making this switch would improve overall air quality and lower carbon emissions.

Lithium batteries are what allow electric vehicles to travel several hundred miles on one charge. Their capacity for energy storage is well known, but so is their tendency to occasionally catch on fire—an occurrence known ...

A team of researchers including University of New Mexico economics professor Andrew Goodkind is addressing the deadly problem of particulate matter air pollution in the U.S. and how to best mitigate it.

A team of engineers at the University of California, Berkeley and the Keck Graduate Institute (KGI) of The Claremont Colleges combined CRISPR with electronic transistors made from graphene to create a new hand-held device ...

Electrical engineering

Electrical engineering, sometimes referred to as electrical and electronic engineering, is a field of engineering that deals with the study and application of electricity, electronics and electromagnetism. The field first became an identifiable occupation in the late nineteenth century after commercialization of the electric telegraph and electrical power supply. It now covers a range of subtopics including power, electronics, control systems, signal processing and telecommunications.

Electrical engineering may or may not include electronic engineering. Where a distinction is made, usually outside of the United States, electrical engineering is considered to deal with the problems associated with large-scale electrical systems such as power transmission and motor control, whereas electronic engineering deals with the study of small-scale electronic systems including computers and integrated circuits. Alternatively, electrical engineers are usually concerned with using electricity to transmit energy, while electronic engineers are concerned with using electricity to transmit information.
